WOODEN PAVEMENT.

SPECIFICATION forming part of Letters Patent No. 343,162, dated June 8, 1886.

Application filed May 28, 1884. Renewed May 6, 1886. Serial No. 201,403. (No model.) Patented in England January 1, 1884,

No. 138, and in France February 2, 1884, No. 148,621.

To all whom t may concern:

Be it known that l, J oHN McGREGoR GEOET, a subject of the Queen of Great Britain, residing at l5 Abbey Road, St. Johns Vood, Lon- 5 don, in the county of Middlesex, England, physician, have invented new and useful Improvements in Wooden Paving, of which the following is a speciiication.

My invention -relates to the paving with [o wooden blocks of roads, alleys, paths, or other ways or spaces, and has for its object to produce a wooden pavement that will keep comparatively dry, and will not be liable to get out of shape, as is the case with Wooden pavement of the ordinary descriptions heretofore usually employed. rFor this purpose I forin in the lower portions of the wooden pavingblocks grooves or channels, and I lay these grooved or channeled blocks in rows transverse 2o to the road or Way, so that the groove or channel of one block aligns with those of the blocks adjoining it. Thus there is formed across the road or way under the wooden blocks and between them andthe asphalt, concrete, or other 2 5 surface whereon they rest a series of channels or passages. At the sides ofthe road orway blocks are laid yhaving in them grooves or channels arranged lengthwise of the road or way, and the transverse channels or passages are con- 3o nected with these longitudinal channels or passages, so that water can iiow by the transverse into the longitudinal channels or passages, and thence to gullies or drains.

By my invention thepavement, being kept comparatively dry, will not be liable to rot, will be more pleasant to travel upon, and will afford a better foothold to draft-animals than is the case with ordinary wooden pavement. In the accompanying sheet of illustrative drawings, Figure I is a plan or top View of three transverse wooden paving-blocks, and Fig. II is an end view of the same. Fig. III is a plan or top view of one of my improved longitudinal wooden paving-blocks with portions of three adjacent transverse blocks, and Fig. IV is a vertical section of the same in the line x x. Fig. V is a plan or topview to a smaller scale of a portion of a road or way, showing the manner in which my improved 5o paving-blocks are arranged.

a a are wooden paving-blocks, which may be ofthe ordinary form, but each of which is provided at its lower surface with a groove, channel, or passage, b,which may be of any desired cross-sectional form. These blocks, 55.

which I term transverse paving -loloeks,

are arranged in rows transverse to the road or Way upon which they are laid, and in such manner that the groove or. channel b of all the blocksin such row shall he in line, as shown in Fig. V.

c c are wooden paving-blocks, which may also be of ordinary form, but each of which is provided at one side of its lower surface with a longitudinal groove, channel, or passage, d. These blocks c, which I call longitudinal paving-blocks7 are arranged longitudinally, and at each side of the road or way in such manner with relation to the blocks a that the grooves, channels or passages b are in commu- 7o nication with the grooves, channels, or passages' d, as clearly shown in Figs. III, IV, and V.

`Z is an asphalt, concrete, or other bed or road upon which the blocks are laid, and f the grid of a gully or trap in connection with the drains. It will thus be evident that any water which may iind its way between the paving-blocks and the bed upon which they rest can readily iiow by the transverse 8o grooves, channels, or passages, into the longi- Y -tudinal grooves, channels, or passages, and

thence to the gullies and drains.

It will be readily understood that I may employ grooves, channels of passages of vari- 8 5 ons forms in transverse section; also, that cach block may have more than one channel or passage in it.

By my invention, as above stated, the pavement, being kept comparatively dry, will not be liable to rot, itwill be more pleasant to travel upon than wooden pavement as heretofore usually constructed, and will afford a better foothold to draft-animals than is the case with ordinary wooden pavement. Roads or ways constructed as above are also coinparatively noiseless.

Having` thus described the nature of my said invention, and the manner of carrying it into practical effect, I hereby reserveto Ico myself the right to vary the dimensions, prol portions, and details as may be found desiraA ble in practice.

What I claim asrmy invention, and desire 5 to have secured to me according to law, is In a Wood pavement, the blocks a, with grooves b, in combination with the blocks c, with openings d, and the grid f, al1 arranged substantially as and for the purpose set forth.

In testimony that I claim the foregoing as xo my invention I have signed my name, in presence of two Witnesses, Ythis 1st day of April, 1884.

JOHN MCGREGOR CROFT.
